Very Nice:)Good benchmark for me:) It's basically using the same algorithms (well I don't use MacCormack advection scheme yet - but it's first on my todo list), and memory usage optimization are before me , so expect the same (or slighty lower - OpenCL drivers issues:) performance from me in next few weeks keep your's fingers crossed

Jens, can you give a try to the version attached to this message ? I changed the way OpenCL memory objects are used and context is allocated.

Dade, you are nearly done, you seem to got the culprit I saw you did same as me removing the &event setting NULL, will try now to get the image in viewport back ( with cpu it works btw )EDIT: no luck with image, just to be clear, it behaves as all is rendered, more black=faster and such, just no image to be seen, maybe a wrong type used ?

running now, but full output missing...

The 70000k come from rendering mostly black image atm i think, but thats a great progress indeed, fantastic Dade My frustration vanished CPU gives now 9000k, from 1500k before ! All renderered with simple.scn.

Edit2: hmm...cornell.scn gives 1500 on cpu but over 70000 on gpu too, it apears that i do render empty space here ( same speed as simple with gpu) so the empty viewer is explained by that i fearObservation: i can do camera-actions and the little dot in the middle of the view is moving, so something must be in the scene/view, but again clueless what fails atm

It looks like your driver doesn't support OpenCL ICD (i.e multi-platform support), may be are you using an old NVIDIA driver ? ATI has added the support in SDK final 2.0 (and at that point I added the support too),

@Jens: may be a problem with OpenCL camera buffer ? Have you tried to run simple.scn instead of cornell.scn ?
